Fig. 2 is the block diagram of overview of the control circuit of expression cage door device shown in Figure 1.In the drawings, the on-off action of car door 2a, 2b is by 19 controls of open and close controlling portion.Open and close controlling portion 19 for example is installed on the car 1, the door motor (not shown) of controlling and driving car door 2a, 2b.
Signal from the 1st and the 2nd pick up camera 13,14 is sent to image processing detection unit 20.When the 1st and the 2nd car door 2a, 2b opened and closed, image processing detection unit 20 was judged only not blocked by object (obstacle) from the 1st and the 2nd illuminator 11,12 according to the signal from the 1st and the 2nd pick up camera 13,14.
The the 1st and the 2nd illuminator the 11,12, the 1st and the 2nd pick up camera 13,14, image processing detection unit the 20, the 1st and the 2nd light projector 15,17, alarm device 6 and open and close controlling portion 19 are by master control part 21 controls.Signal from image processing detection unit the 20, the 1st and the 2nd light-receiving device 16,18 and open and close controlling portion 19 is transfused to master control part 21.
When car door 2a, 2b opened and closed, master control part 21 made from the 1st and the 2nd illuminator 11,12 irradiates lights, and had or not object near monitoring car gangway 1a.And, master control part 21 at least at car door 2a, make when 2b opens the door from the 1st and the 2nd light projector 15,17 outgoing beams, and have or not object near monitoring the 1st and the 2nd vertical frame 3a, 3b.In addition, master control part 21 sends the switching order of car door 2a, 2b according to the testing result of object to open and close controlling portion 19.
Open and close controlling portion 19, image processing detection unit 20 and master control part 21 all are made of microcomputer.But, also can utilize public microcomputer constitute in open and close controlling portion 19, image processing detection unit 20 and the master control part 21 at least both.And the control setup of embodiment 1 has open and close controlling portion 19 and master control part 21.
And it is the 1st detecting device 22 of the object of car gangway 1a that detection is present between vertical frame 3a, the 3b, has the 1st and the 2nd illuminator the 11,12, the 1st and the 2nd pick up camera 13,14 and image processing detection unit 20.In addition, detect the 2nd detecting device 23 that is present near the object of vertical frame 3a, 3b and have the 1st and the 2nd light projector 15,17 and the 1st and the 2nd light- receiving device 16,18.
At this, for fear of the mutual interference that occurs light in the 1st detecting device 22 and the 2nd detecting device 23, the light wavelength that preferred the 1st detecting device 22 adopts is different with the light wavelength that the 2nd detecting device 23 adopts.For example, preferably illuminator 11,12 sends red light in the 1st detecting device 22, and 13,14 in pick up camera is taken red, and light projector 15,17 penetrates near infrared light in the 2nd detecting device 23, and 16,18 of light-receiving devices are subjected to the light near infrared light.
Below, the method for inspection of the object that is undertaken by the 1st detecting device 22 is described.At first, will when not lighting, illuminator 11,12 be taken in the image processing detection unit 20 by view data α and the view data β when illuminator 11,12 is lighted from pick up camera 13,14.And, the difference image γ of computing behind the view data β subtracted image data α.When carrying out the supervision of object, carry out such action repeatedly.
By carrying out this difference processing, only remaining with the emitting surface 11a after the exterior light removal on every side, the picture of 12a in difference image γ.Therefore, when being the summit with pick up camera 13,14, being when not having the object of shading light in two leg-of-mutton monitor areas on base with emitting surface 11a, 12a, the picture of the emitting surface of remaining continuous straight line shape as shown in Figure 3 in difference image γ.
Relative therewith, when in monitor area, having the object of shading light, because the part of light is blocked, therefore remaining picture in difference image γ as Fig. 4 or emitting surface shown in Figure 5.That is, in difference image γ shown in Figure 4, the picture of emitting surface is cut to and a plurality ofly becomes discontinuous.And in difference image γ shown in Figure 5, when common (Fig. 3) is short for the length of the picture of emitting surface.The picture that image processing detection unit 20 detects emitting surface becomes when picture discontinuous, emitting surface shortens or the picture of emitting surface disappears, and is judged to be between vertical frame 3a, the 3b to have object, and will represents that the signal of this content sends to master control part 21.
Below, the method for inspection of the object that is undertaken by the 2nd detecting device 23 is described.When having object between the 1st light projector 15 and the 1st light-receiving device 16, the light income from the light of the 1st light projector 15 in the 1st light-receiving device 16 descends.Equally, when having object between the 2nd light projector 17 and the 2nd light-receiving device 18, the light income from the light of the 2nd light projector 17 in the 2nd light-receiving device 18 descends.And, reaching pre-set threshold when following at the light income of the 1st or the 2nd light-receiving device 16,18, master control part 21 is judged to be near vertical frame 3a, 3b and has object.
Below, Fig. 6 is the diagram of circuit of the expression action of master control part 21 when opening the door shown in Figure 2.After car 1 rests in the stop floor and before the schedule time of the actual action that begins to open the door of car door 2a, 2b (for example before the several seconds), master control part 21 makes the detection action beginning of the object that is undertaken by the 1st and the 2nd detecting device 22,23, judges to have or not object (step S1).At this moment, if do not detect object, then begin common opening the door (step S2) in normal timing.
Relative therewith, when detecting object, give a warning by at least any one party in read out instrument 5 and the alarm device 6, make passenger in the car 1 away from car door 2a, 2b (step S3).Specifically, play the voice (perhaps alarm tone) of storage in advance, for example " will open the door from alarm device 6.Please away from door." wait broadcasting, perhaps on read out instrument 5, show the Word message of storage in advance.And, after no longer detecting object, begin common opening the door.
After beginning was opened the door usually, the detection of the object that is undertaken by the 1st detecting device 22 action stopped, and only made the detection action of the object that is undertaken by the 2nd detecting device 23 continue (step S4).If the 2nd detecting device 23 does not detect object, action (step S5) then continues to open the door.And, continue the detection action of the object that undertaken by the 2nd detecting device 23, move to a full open position of coupler (step S4～S6) up to the 1st and the 2nd car door 2a, 2b.And, if the 1st and the 2nd car door 2a, 2b are moved to a full open position of coupler, then end process at the state that the 2nd detecting device 23 does not detect object.
On the other hand, when detecting object by the 2nd detecting device 23 in the course of action that opening the door, making the action of opening the door stop (step S7) for the time being, carrying out alerts action same as described above (step S8).And, under the state that the action of opening the door stops, continuing alerts action, no longer detect object up to the 2nd detecting device 23.
